Hourly wage calculator — what you actually earn per hour after tax
Rate, hours and weeks in — annual, monthly, weekly and true after-tax hourly pay out, with a National Minimum Wage check built in.
Multiply your hourly rate by weekly hours and paid weeks to get annual gross, then tax works as for any salary. £15/hour full-time (37.5 hrs, 52 weeks) grosses £29,250 and takes home £24,579.60 in 2025/26 — a true after-tax rate of £12.60/hour. The National Minimum Wage for age 21+ is £12.21/hour.

How to work out hourly take-home
PAYE doesn’t know about hours — it taxes your annual total. So the honest way to get an after-tax hourly rate is to annualise first (rate × hours × weeks), run the full tax and NI calculation on that, and divide the take-home by the hours you actually work. That final number — take-home per hour — is what an extra shift is really worth to you.
Watch the weeks figure: 52 assumes every week is paid (normal for employees, whose holiday is paid). If some weeks are unpaid, both your gross and your tax fall — but because of the personal allowance, your after-tax hourly rate actually improves slightly as income drops.
